Definitions
- the present invention relates generally to devices for trimming grass, weeds and the like and, in one of its aspects, to a device which is convertible between a conventional trimming device and an edger.
- a carriage for a rotary trimming device which allows connversion of the device to an edger is shown in U.S. Pat. No. 4,287,709 and U.S. Pat. No. 4,343,139 of Lowry et al. These carriages show the use of a fifth wheel for tipping the carriage and the attached trimming device at an angle to aid in certain edging type operations.
- a trimming device in accordance with the present invention, includes a motor, a housing for the motor and a cutting element connected to the motor in a conventional fashion.
- the device also inlcudes a carriage and means for mounting the motor housing on the carriage.
- the means for mounting allows the motor to be mounted in at least two positions. In a first position, the axis of rotation of the cutting element is substantially vertical so that the cutting element swings in a substantially horizontal plane. In a second position, the axis of rotation for the cutting element is substantially horizontal so that the cutting element sweeps in a substantially vertical plane.
- the mounting means includes a vertical axis pivot means, a support member rotatable with respect to the carriage in a substantially horizontal plane about the vertical axis pivot means and a horizontal axis pivot means spaced apart from the vertical axis pivot means.
- the motor housing is rotatable about the horizontal means with respect to the support member.
- the support member supports the housing in front of the carriage in the first position and supports the housing to the side of the carriage when in the second position.
- the trimming device of the present invention operates as a conventional trimming device when the motor is supported in the first position and as a conventional edger when the motor is supported in the second position without the need for tipping the entire carriage or holding the device at an odd angle.
- the user can operate the device from a normal and comfortable upright position as a trimmer or an edger.
- FIG. 1 is a perspective view of a preferred form of a trimming device according to the present invention in position to operate as a conventional trimming device;
- FIG. 2 is a perspective view of the trimming device of FIG. 1 with the motor in position to operate as an edger.
- Trimming device 10 includes a motor of a conventional sort which is not shown but is enclosed within housing 12 for the motor.
- a cutting element 14 made of nylon or similar material is connected to the motor so as to be rotatable about an axis for cutting grass, weeds and the like.
- a carriage 16 supports cutting device 10, and means 18 for mounting motor housing 12 on carriage 16 supports motor housing 12 in a first position in which axis of rotation of cutting element 14 is substantially vertical. As a result, cutting element 14 swings in a substantially horizontal plane in the manner of a conventional trimming device.
- Means 18 for mounting motor housing 12 on carriage 16 includes a vertical axis pivot means such as bolt and wing nut 20 and support member 22 which is rotatable with respect to the carriage in a substantially horizontal plane about bolt and wing nut 20.
- a horizontal pivot means such as bolt and wing nuts 24 is spaced apart from bolt and wing nut 20.
- Motor housing 12 is rotatable about bolt and wing nuts 24 in a substantially vertical plane.
- motor housing 12 is in a second position in which support member 22 supports it to the side of carriage 16 and in which the axis of rotation for cutting element 14 is substantially horizontal so that cutting element 14 swings in a substantially vertical plane.
- the second position was achieved by first rotating motor housing 12 about bolt and wing nuts 24 from a substantially vertical position to a substantially horizontal position, then re-tightening the wing nuts to hold it in place. Support member 22 was then rotated in a substantially horizontal plane about bolt and wing nut 20 until motor housing 12 was to the side of carriage 16. Then the wing nut was re-tightened.
- Carriage 16 shown for illustration purposes is a sled type carriage having runners 26 and 28 connected by a support platform 30. Runners 26 and 28 are preferably constructed from a light tubing and are reinforced by webbing 32 and 34. A handle 36 is provided for the convenience of the user in pushing and guiding the trimming device. Carriage 16 shown for purposes of illustration is also described in co-pending application Ser. No. 551,126, filed Nov. 14, 1983, but a conventional carriage such as a wheeled carriage could also be used.
